Refractory Panel Repair in Alamo Heights, TX

Surface hairline cracks can often be sealed with high-temperature refractory caulk. If you can fit a nickel's edge (about 1/16") into the crack, it runs through the panel, or the panel is spalling or pulling away, it's past repair and needs replacement. A tech checks crack depth, not just width, before deciding.

Refractory panels are the heat barrier between the fire and the steel firebox shell and the combustible wall behind it. Once a crack lets heat reach the metal or framing, the firebox no longer performs the way it was tested and listed to, so a through-crack isn't cosmetic.

Applying refractory caulk is simple; the hard part is judging whether the crack is still within the manufacturer's allowable limit or past it. Sealant only buys time on shallow cracks — on a through-crack it hides the problem rather than fixing it, so it's worth having the depth assessed.

A straightforward sealant repair is usually one visit, but the caulk needs curing time before the first fire (follow the product's cure schedule). The starting price covers minor crack sealing; cost rises with panel condition and how many cracks need treatment, quoted in writing first.
